Hi everybody,

Sorry for not posting to the corresponding thread, but I get this error when I try to post there

 ![IMG_0111](https://forum-cdn.knime.com/uploads/default/original/3X/5/4/5484e88880e688a4ee21bab550aec7e1aa9d5017.jpeg)

I´m taking the L3-CD self-paced course and when I reach exercise Session 2 / exercise 03b and also in Session 3 / exercise 2, the first step is to connect to a PostgreSQL database. Instruction says : “provide the hostname and database name shared by the trainers as well as your username (_ **userXX** _), password (_ **userXX** _), and schema (_ **userXX** _)”. I don’t think I received these credentials, so I can´t connect to the database.

Please help, thank you.

@dracpet if this is a live session you should have received a login I assume. If you [do this on your own](https://hub.knime.com/knime/spaces/Education/Courses/L3-CD%20Continuous%20Deployment%20and%20MLOps~Y3LYnJ-xhP7AKUU9/), you can either set up a [PostgreSQL](https://hub.knime.com/search?type=Workflow&tag=postgresql&sort=best) database on you machine or just use the “customer\_data.table” on your local machine:

Problem solved, I had the instructor-led course workflow and not the self-paced course workflow. Thank you for your workflow and help.
